They secrete Hydrochloric acid in the stomach to help break down peptides.
The parietal cells of the stomach secrete hydrogen ions and chloride ions, which combine to form hydrochloric acid.
Hydrochloric acid is secreted by the parietal cells in the stomach lining. These cells are responsible for producing the acidic environment in the stomach that aids in digestion.
Parietal cells
Gastric glands which secrete:HClRenninpepsin
No, pepsinogens are not produced by parietal cells; they are produced by chief cells in the stomach. Parietal cells are responsible for secreting hydrochloric acid and intrinsic factor. Pepsinogens are inactive precursors of pepsin, an enzyme that aids in protein digestion, and they are activated into pepsin in the acidic environment created by the hydrochloric acid from parietal cells.
The parietal cell has several unique organelles, including mitochondria for producing energy, secretory vesicles for storing and releasing digestive enzymes, and tubulovesicles for transporting and recycling cellular materials. Additionally, parietal cells contain an extensive network of tubulovesicles called canaliculi, which are involved in the secretion of hydrochloric acid into the stomach.
Parietal cells
Hydrochloric acid is secreted by the parietal cells in the stomach. They are responsible for producing the acidic environment necessary for digestion and killing bacteria in the stomach.

Yes, parietal cells (like all cells) have a cell membrane. Parietal cells have a huge surface area (their membrane has deep folds called canaliculi).
This is the IB answer key to this Question: secretory cells arranged in layer one cell thick; cells contain secretory vesicles; cells are grouped in acini; surrounded by basement membrane; cells adjacent to duct/lumen;
